A restricted vent or the wrong vent hose can cause the early demise of heating parts on a dryer. Be sure you do not have foil duct on back...use the semi-rigid type instead. The instructions that come with the dryer are pretty clear in this regard.

I changed out the thermistor and still get the same code t5. In service mode, it gives me a code 1 which also points to the thermistor. The resistance across the new thermistor is 11k ohms where the old one was around 17k ohms. I checked the resistance across the thermostat 1 which is next to the thermistor and it shows .1 ohms, which should be good. I also thoroughly cleaned all areas where lint could accumulate. Any other suggestions?
